What would be the best way to upload data to a form to update with the Angular JS framework?

// create the module and name it scotchApp
var scotchApp = angular.module('scotchApp', ['ngRoute']);

// configure our routes
scotchApp.config(function($routeProvider) {
    $routeProvider

        // route for the home page
        .when('/', {
            templateUrl : 'pages/home.html',
            controller  : 'mainController'
        })

        // route for the book page
        .when('/books', {
            templateUrl : 'pages/book.html',
            controller  : 'booksController'
        })

        // route for the client page
        .when('/books/:id', {
            templateUrl : 'pages/book.html',
            controller  : 'booksController'
        })

        .otherwise({ redirectTo : "/"});
});

// create the controller and inject Angular's $scope
scotchApp.controller('mainController', function($scope) {
    // create a message to display in our view
    $scope.message = 'Everyone come and see how good I look!';
});

scotchApp.controller('booksController', function($scope,$http,$routeParams) {
    $http.get('script/list.php').then (function(response){$scope.datos = response.data.tasks;});
    // Add new task
$scope.addTask = function () {
    var add = confirm('desear adicionar datos ?');
    if (add==true) {
    $http.post('script/create.php', {
        dato: $scope.dato
    })
        .then(function success(e) {

            $scope.errors = [];

            $scope.datos.push(e.data.dato);

        }, function error(e) {
            $scope.errors = e.data.errors;
        });
        $scope.dato = {};
    $scope.edit = false;
    }
};

$scope.editData = function(index){
    var edt = confirm('desea editar dato');
    if (edt==true) {

    $scope.dato = $scope.datos[index];
    $scope.edit = true;

    }
};

    // update the task
$scope.updateTask = function () {
    var upd= confirm("estas seguro editar"); 
    if (upd==true) {


    $http.post('script/update.php', {
        dato: $scope.dato
    })
        .then(function success(e) {
            $scope.errors = [];

        }, function error(e) {
            $scope.errors = e.data.errors;

        });
    $scope.dato = {};
    $scope.edit = false;
};
}

    // delete the task
$scope.deletData = function (index) {

    var conf = confirm("Estas seguro querer eliminar estos datos" + index );

    if (conf == true) {
        $http.post('script/delete.php', {
            dato: $scope.datos[index]
        })
            .then(function success(e) {

                $scope.errors = [];
                $scope.datos.splice(index, 1);


            }, function error(e) {
                $scope.errors = e.data.errors;
            });

    }
};

$scope.deleteData = function( nom ) {
    //alert (nom);
    if ( confirm("Seguro?") ) {
    $http.get('script/delete.php?dato='+ nom ).success(function(data){
        if( data.err !== undefined ){
            window.location = "#/books";
            return;
        }
        $scope.alumno = data;
    });
    }
}


});

scotchApp.controller('bookController', function($scope, $routeParams, $http) {
    var id = $routeParams.id;

    $scope.myCallback = function (valueFromDirective) {
    console.log(valueFromDirective);
    };

    $scope.alumno = {};
});
